This error message typically occurs when you are trying to use a variable or function that has not been defined or does not exist in the current scope. In this case, it seems like you are trying to use the variable "sm", but it has not been defined. It is possible that you meant to use the built-in function "sum" instead. Double-check your code and make sure all variables and functions are properly defined.

NameError: name 'pd' is not defined. Did you mean: 'id'?
NameError: name 'pd' is not defined. Did you mean: 'id'? 这个错误通常是因为在使用pandas库之前没有正确导入它。要解决这个问题,你需要在代码中添加正确的导入语句。
以下是一个示例,演示了如何正确导入pandas库并使用它:
```python
import pandas as pd
# 在这里使用pandas库
# 例如,创建一个DataFrame对象
data = {'Name': ['John', 'Emma', 'Mike'],
'Age': [25, 28, 30]}
df = pd.DataFrame(data)
# 打印DataFrame对象
print(df)
```
在这个示例中,我们首先使用`import pandas as pd`语句导入pandas库。然后,我们创建一个包含姓名和年龄的字典,并使用该字典创建一个DataFrame对象。最后,我们打印出这个DataFrame对象。
请确保在使用pandas库之前正确导入它,这样就不会出现NameError: name 'pd' is not defined的错误。
name 'pid' is not defined. Did you mean: 'id'?
The error message you received indicates that the identifier 'pid' is not defined in the scope where it is being used. It seems like you may have misspelled the keyword 'id' as 'pid'.
In Python, 'id' is a built-in function that returns the identity (memory address) of an object. Therefore, you can try replacing 'pid' with 'id' in your code and see if it resolves the issue.
